Niederspannungs-Impulsfilter

First, the working principleLCMD-type low-pressure pulse bag filter off-line cleaning of gas purification filter for the outside ceremony. Dusty gas diversion tube into each unit from the filter room, bags in the design of the end of the vertical distance from the inlet catchy enough, reasonable space, natural air flow through appropriate diversion and distribution of large particles of dust to the filter with the air chamber directly into the hopper after the remaining dust in the diversion system under the guidance of the box with the air filter into the area, dust filter region box set with flowers plates, dust collector bag assembly with a spring ring up plate sealing connection with the flower, forming clean gas area (the box) and the dusty gas area (in box) of the separation. Dusty gas in the cabinets under negative pressure through the filter bag, dust bag blocked by adsorption in the bag's outer surface, filtered clean gas through the bag into the box and through the exhaust emissions Explorer .With the condition of the filter, when the bag reaches a certain amount of surface area, by the cleaning control device (differential pressure or time, manual control) by setting program to open the electromagnetic pulse valve injection, compressed gases to the order of a very short time each pulse valve injection through the nozzle tube several times in the jet induced gas in the air into the bag, the formation of the air waves, so the bag to the bottom of the bag produced by the rapid expansion and shock and vibration, causing the bag to form a comprehensive jitter from the inside The role of outside air cleaning, removing attached to the outer surface of the dust bag to achieve the purpose of cleaning.Fall into the hopper of the dust concentration by sending ash facilities. Set the heating device ESP ash bucket, to prevent fouling compaction; block device configuration compressed air cannon broken arch, to ensure that dust hopper discharging smoothly. In the dust collector hopper level meter is installed for level detection.Control of dust (including dust control, etc.) using PLC programmable controller for automatic control. Complete the implementation of dust control system unattended automation control system can be feedback to the factory to accept factory system remote control. Second, characteristics 1. special structural design, and effectively avoid the paste bag, boiler tube, flue gas temperature anomalies such as the adverse effects of dust, dust to ensure the safe and normal operation. 2. high degree of automation, injection timing, spacing, by computer control, automatically, can be timed or constant pressure cleaning. 3.more than 99.99% removal efficiency, emissions concentrations in 30mg/Nm3 below. 4. can handle 140 200 °C high temperature smoke.
